Researchers have discovered a pair of functional networks in the human cerebral cortex that are not present in the brains of rhesus monkeys, leading them to theorize that the networks were added during the evolution from ancient primates to the modern day homo sapiens.

Researchers have for the first time shown that they can control the behavior of monkeys by using pulses of blue light to very specific brain cells.
